Method like "instanceof" for custom views in Android?

Question

I inflate some layouts during running of App and store them in a variable of type View.I know that I can set a Tag for view after inflating it and check it to detect it's type,but is there another way to detect it?For example a method like instanceof?

Are you talking about this: http://stackoverflow.com/questions/2695646/declaring-a-custom-android-ui-element-using-xml or something else? — Morrison Chang, Apr 08 '13 at 05:29
@MorrisonChang Oh,no... .It is in about creating and using customview from xml.But my question is in about how I can detect my customview is inflated from which layout? — hasanghaforian, Apr 08 '13 at 05:34
@hasanghaforian you mean you want to get the file name of the inflated xml file? — Pragnani, Apr 08 '13 at 05:42
@hasanghaforian Nothing is impossible...just set contentDescription for your view, and identify your view based on the contentDescription — Pragnani, Apr 08 '13 at 05:48

Try something like this

 View yourView1=(View)findViewById(R.id.yourView1);

     boolean isMyView=false; 
        try{
           YourView yv=(YourView)yourView1;
     isMyView=true;
        }
        catch (ClassCastException e)
        {
     isMyView=false; 
            e.printStackTrace();
        }

    if(isMyView)
       {
         //OK it is yourView
        }

That do not work for views that are inflated from .xml files. – hasanghaforian Apr 08 '13 at 06:14
